Hi all,
I have a 2017 Platinum. I have already programmed a trailer. When I try to add pro trailer assist it makes me add another trailer and name it. Is there a way to just program to the trailer I have already listed or do I need to delete the trailer and start over? Thanks.

 

Don't know what "programmed a trailer" means, other than when you plug in a trailer, the truck sees it, and you put a name on it. Not much programming there.

When you go to add a trailer in Pro Backup Assist, if it sees any existing trailer you'd be able to scroll up or down to it. If you see nothing then yes, you need to add it again.

There is a lot more to setting up (programming) a trailer in Pro Backup Assist than just hooking up a trailer and naming it.

These are the steps:


1. Select the option to add a trailer in the
instrument cluster menu, using the
steering wheel control. See General
Information (page 109).
2. Add a personalized name for the trailer
using the screen prompts. Use the
down arrow to scroll to the desired
letter and then press the right arrow to
advance to the next letter. Press OK to
continue.
3. Select the type of trailer brake system
for the trailer you are adding.
4. Select the brake effort level for the
trailer.
Note: The default option is low. This is
recommended for most trailers. If the
trailer's brakes require more initial voltage,
or if you prefer more aggressive braking then
select the other options as required.
5. Select the trailer type.
Some examples of conventional type
trailers are shown below.
Note: You cannot use the system with the
types of trailers marked with the cross.
The system only works with
conventional trailers. It does not work
with other types including goose neck
and fifth wheel.

Follow the information display prompts.
Step 3: Place the Sticker on the Trailer
Frame
The supplied sticker must be placed in an
area visible by the Rear View Camera.
Note: The cargo and trailer hookup lamps
turn on automatically to improve visibility.
Note: An assistant can help to carry out the
following procedure.
Note: Make sure nothing can obstruct the
Rear View Camera's view of the sticker. For
example, items such as a jack handle or
wiring.
Note: Position the sticker on a flat, dry and
clean horizontal surface. For best results
apply the sticker when temperatures are
above 32°F (0°C).

Note: Do not move stickers after they are
placed. Do not re-use any stickers if
removed.
Note:Additional stickers may be purchased
through your Ford Dealers parts department.

Use the supplied measurement card, a
tape measure and pen to carefully mark
the area where to attach the sticker
(supplied in the back cover pocket of your
quick start guide). Make sure the whole
sticker is within the zone between the two
arcs or distance markers on the diagram,
and is also visible in the Rear View Camera
display.
Step 4: Take Measurements
After the sticker is correctly placed on the
trailer you must take some key
measurements.
Note: Accurate measurements must be
taken for the system to operate properly.
Note: Round measurement figures to the
nearest half inch.
Note:Round upward if the measured length
is a quarter inch or greater. Round
downward if the measure length is less than
a quarter inch. For example 12.25 in
(31.11 cm) would be rounded up to 12.50 in
(31.75 cm). 12.13 in (30.8 cm) would be
rounded down to 12.00 in (30.48 cm).
Note: Use consistent metric or imperial
units as required by your country or vehicle.
Record the four key distances (A, B, C, D)
as required by the measurement card.
Record the trailer name for these
measurements.
E209806
A
B
C
D
D
Distance A
The horizontal distance from the license
plate to the center of the ball hitch on the
trailer.
Distance B
The horizontal distance from the center of
the ball hitch to the center of the sticker.
Distance C
The distance from the Rear View Camera
to the center of the sticker.
Distance D
The horizontal distance from the tailgate
to the center of the trailer axle (single axle
trailers), or the center of the axles (trailers
with dual axles or more).

Step 5: Enter Measurements Using the
Information Display
Using the recorded measurements, enter
the required data into the system. Follow
the on screen prompts to enter each of the
measurements taken in step 4. When all
four distances have been entered, a
confirmation display will appear. Check
the values are correct before proceeding,
or go back to change any if required.
Step 6: Confirming the Sticker Location
Check the Rear View Camera display to
see if the sticker is identified by the system
and marked with a red circle.
Confirm that the red circle is correctly
located over the sticker image in the
display. The on screen prompt will ask you
to confirm this.
Note: If the system cannot locate the
sticker try cleaning the camera lens, and
also make sure the sticker is within the green
zone as indicated in step 3. Check your
measurements to make sure you measured
from the correct points.
Calibrating the System
To complete setup, drive your vehicle
straight forward between 4 mph (6 km/h)
and 24 mph (39 km/h) following the on
screen prompt.
Note: If you move the steering wheel during
this procedure, the calibration pauses.
Note:We recommend that you do not do
this at night.
A message will be displayed during
calibration and after calibration is
complete

 

I use a different trailer back up system...

 

I'm with ya on that one!

 

I did all the "programming" for my boat & trailer, but not my TT as I don't plan on using the assist function when spotting the TT. I have a wife for that. LOL I did all the programming and adding in one step, so you may just need to delete the trailer and start over again. I do notice the truck wants me to add trailer assist to the TT but it doesn't hound me about it not being programmed in with all of the measuring required.

 

I tried the backup assist, not for me. I live on a busy street, get one shot to back in before the traffic gets angry. It's a narrow street and while backing in, camera loses sight of the sticker and shuts off. Like a dumb *** I went to turn it all back on and that just wasted time I didn't have. Maybe I'll try it again if I ever have to back down out of a mountain

 

I agree with Mudder. Got a new 2018 f150 and if i'm backing up too sharply due to narrow street, or if I'm backing up or downhill (my driveway), the camera looses
the sticker and you're on your own. Very frustrating for a first-timer. Better get used to doing it the old fashion way. Not too hard once you get
the hang of it.
